Description

Energy-saving heating coal stove for northern rural areas

Technical Field

The technical scheme relates to a heating coal integrated furnace, in particular to a heating energy-saving coal furnace in northern rural areas.

Background

As is well known, in northern rural areas of China, coal stove heating and cooking are often adopted, and heat generated by combustion of fuel in the coal stove is hardly utilized except cooking, so that resource waste is caused.

In order to overcome the situation, chinese patent CN02253806.2 discloses a water heater coal stove, wherein an annular container-water heater layer for containing water is arranged around the coal stove, the water in the container is heated by using the combustion temperature of the coal stove, and hot water is fully burned by using the combustion heat of fuel while cooking, so that the resource utilization rate is improved. Although the technology improves the heat utilization rate compared with the traditional coal stove, the utilization rate is not high, and the main reasons are as follows: 1. the coal stove is unreasonable in structural arrangement, the side surface of the coal stove is a vertical surface, the heat exchange effect is poor, and the improvement is still needed; 2. the gas temperature after the fuel combustion is higher, still can heat the object, and the device is not utilized, leads to the waste heat utilization rate lower, and waste heat utilization is insufficient.

The specific technical scheme is as follows.

The utility model provides a rural heating energy-saving coal stove in north, including furnace body and furnace body, be equipped with water inlet and delivery port on the furnace body, the furnace top is the pot mouth, and the furnace is equipped with the reservoir chamber all around and separates through the oven, characterized by, reservoir chamber and side intermediate layer intercommunication, one side of reservoir chamber is equipped with the smoke chamber, and the smoke chamber top communicates through last passageway with the furnace top, and the smoke chamber communicates through the lower passage with the flue, and the smoke chamber is indoor to be distributed with many heat exchange tubes, and the heat exchange tube is with the side intermediate layer intercommunication of left and right sides.

The rear part of the furnace body close to the flue is provided with a rear interlayer which is communicated with the side interlayer.

The front part of the furnace body, which is close to the water storage chamber, is provided with a front interlayer which is communicated with the side interlayer.

An upper interlayer is arranged above the furnace body and is communicated with the side interlayer.

The hearth is a table-shaped space (or a conical space) with a small upper part and a large lower part.

The heat exchange tube is a stainless steel heat exchange tube.

The side wall of the hearth can be provided with a fueling port and a soot cleaning port.

The water inlet is positioned at the outer side wall of the interlayer below the flue, and the water outlet is positioned at the outer side wall of the interlayer above the water storage chamber.

The technical scheme is as follows: when the saucepan is placed at the pan opening, a relatively closed space is formed at the top of the hearth, high-temperature gas (containing smoke) can be forced to enter the smoke chamber through the upper channel at the top, and the water in the heat exchange tubes is heated by the high-temperature gas in a heat exchange mode due to the fact that a plurality of heat exchange tubes for containing water are distributed in the smoke chamber. Meanwhile, the hearth also continuously conveys high-temperature gas into the smoke chamber through the upper channel, the smoke chamber is in a high-pressure state, and redundant gas enters the flue through the lower channel at the bottom. Because the rear part of the flue is provided with the rear interlayer, the left side and the right side are provided with the side interlayers, the water in the interlayers is heated by the waste heat of the gas in the flue, and the gas and the smoke after being heated are discharged from the top of the flue. Therefore, the high-temperature gas generated by the combustion of the coal stove can be fully applied, more hot water is obtained for people to use under the condition of the same fuel, and the energy is saved. Thereby realizing the purposes of the utility model of high heat energy utilization rate, energy conservation and environmental protection.

The technical scheme is further described as follows:

1. according to the technical scheme, the water storage chambers around the hearth are primary waste heat recovery systems, and are affected by the high temperature of combustion of the hearth, so that the heat obtained by the water storage chambers is the most and the temperature is the highest; the left side interlayer, the right side interlayer, the upper interlayer and the inner heat exchange tubes of the smoke chamber form a secondary waste heat recovery system, and the smoke chamber is filled with high-temperature gas for the first time, so that the heat obtained by the secondary waste heat recovery system is second highest; the left side interlayer, the right side interlayer, the rear interlayer, the upper interlayer and the second heat exchange tube form a three-stage waste heat recovery system, and the gas after heat exchange enters the flue, so that the waste heat is low, and the obtained heat is low compared with the former heat, and the temperature is low. In the technical scheme, water sequentially passes through the three-stage waste heat recovery system, the two-stage waste heat recovery system and the one-stage waste heat recovery system from the water inlet, so that the water is subjected to a very scientific temperature rising process, the flow direction of the water is reciprocal to the direction of smoke, and cold water is gradually heated, so that the heat utilization rate can be further enhanced;

2. in the scheme, interlayers which are mutually communicated are arranged at the front, the back, the left, the right and the upper part of the furnace body, the interlayer is that the water storage space penetrates through the whole smoke path, heat exchange is fully carried out with smoke, and meanwhile, the heat insulation and protection effects are also provided, so that a user cannot be scalded due to touching the furnace body;

3. the flame extends from bottom to top, and the side wall of the hearth is vertical in the prior art, so that the hearth wall can only receive the temperature of the side face of the flame. The hearth is arranged into the table-shaped structure with the small upper part and the large lower part, the hearth wall forms an inclined plane, the heat can be quickly obtained by direct combustion above flame, the contact area of the hearth wall is increased, the heating effect is further enhanced, and the water in the water storage chamber is quickly heated;

4. the upper smoke inlet channel between the smoke chamber and the hearth is arranged above, and the lower smoke outlet channel between the smoke chamber and the flue is arranged below the opposite direction. Similarly, the water inlet is positioned at the outer side wall of the interlayer below the flue, the water outlet is positioned at the outer side wall of the interlayer above the water storage chamber, and water can fully circulate through the whole interlayer, so that the heating effect is improved;

5. in the scheme, water is in the front interlayer, the rear interlayer, the side interlayer, the upper interlayer, the heat exchange tubes and the water storage chamber, and smoke is in the hearth, the smoke chamber and the flue, and the two are in mutually independent and closed spaces, so that the smoke does not pollute the water, and the water heated by the equipment is clean, clear and edible or used by other domestic water;

6. the front, back, left, right and upper words in the technical scheme take one side of the furnace body close to the furnace liner as the front, and one side of the furnace body close to the flue as the back, and the direction words are only convenient for describing and understanding the structure of the scheme.
